DIY pogoplug? or tonidoplug?

Hi all I am a skilled computer user, I primarily work with windows however have played quite a bit with ubuntu and archlinux.
My question is this:
I would like to be able to access files from my home when I am on the go. Currently I use getdropbox and it is a great solution however I have recently been intrigued wih pogoplug and tonidaplug. Since both of these devices are just small computers, couldnt I do this with a computer I already have? How could I securily reproduce similar results on my own and securily access my personal files? How risky would it be?
thanks
